The complete route you’ll tackle is 89 km long, with a difference in height of about 1,700 meters. It is a round-trip itinerary that offers an approach to the final climb on a secondary paved road, known as “ex militare”, which will take you up the Stura Valley away from the main road network, on the shaded side of the ascent, through green woods and a privileged view of the villages in the valley. 

Start from Borgo San Dalmazzo, leave the town immediately by taking the “Via dei Boschi”, largely usable only on foot or by bike. You’ll pass Roccasparvera, Gaiola, Moiola, Demonte and Aisone. A short climb will bring you to the Forte Albertino of Vinadio, and you’ll then reach the hamlet of Pratolungo, from which, following the signs, the real climb begins. 

The first section features hairpin bends with a steady ascent; it then continues up a constant, steep ascent, leaving you a few stretches in which to catch your breath, along the river flanked by stone military structures. Another series of hairpin bends helps you to gain altitude as you climb as far as the great glacial plateau, from which you can see the sanctuary. Once at the detour to the Lombardy hill, you start the last, very challenging 2km, which lead you to the destination.

You’ll return along the same road, and can opt to use the state road, which is faster but also busier.
